Pakistani riot police stand guard, to block supporters of Pakistani Sunni Muslim cleric Tahir-ul-Qadri from entering the high security area Red Zone, who are camping near the parliament, during an anti-government rally in Islamabad, Pakistan, Thursday, Jan. 17, 2013. Pakistan's anti-corruption chief refused a Supreme Court order to arrest the prime minister in a graft case Thursday citing a lack of evidence, in the latest clash between the government and the country's top court. The arrest order issued Tuesday intensified the sense of political crisis in Pakistan, where a firebrand Muslim cleric has been leading thousands in an anti-government protest in the heart of the capital, Islamabad, for the past four days.
